BELT-SHIFTING MECHANISM FOR WASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 234,439, dated November 16, 1880.

Application filed August 30, 1880.

To all whom it may concern Be it known that I, LEOPOLD STERNBER- GER, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Belt- Shifting Mechanism for VVashing-Machines, of which improvements the following is a specitication.

My invention is specially designed for use in connection with the washing-machine for which an application for Letters Patent of the United States was filed by me under date of October '7, 1879, but by proper modifications of constructive detail is likewise applicable to other purposes.

The object of my invention is to provide simple and efficient mechanism forstarting and stoppinga rotatable washingyessel; and to this end my improvements consist in the combination of a shaft and a brakedrum secured thereon, a belt-shifter, a friction-brake, an operating-lever, and a rock-shaft and arms for simultaneously actuating the shifter and brake, all as hereinafter more fully set forth.

In the accompanying drawings, Figure l is an end view, in elevation of a washing-machine embodying my improvements; Fig. 2, a side view,in elevation, of the same, and Fig. 3, a view, in perspective, of the stopping and starting mechanism detached.

My improvements are herein shown as applied in the washing-machine which is set forth in my application for Letters Patent hereinbefore referred to.

The cylindrical washing-vesselA is secured upon a shaft, B, which is rotatablein hearings in a frame, B, and carries a spur-gear, G meshing with a pinion, d, on a counter-shaft, D.

The counter-shaftD carries a fast pulley, D, and a loose pulley, D and a driving-belt from a main or line shaft is shifted from the loose to the fast pulley, or vice versa, according as it is desired to rotate or to stop the movement of the vessel, by shifting'arms c, secured upon a bar, E, which slides in guides 6 upon the frame of the machine, and is operated simultaneously with a friction-band, F, encircling a brake rim or drum, 0 secured upon the shaft B, by a sliding bar or rod, E, which is connected at one end by a bell-crank, 0 with the bar E, and is provided at the other end with a proper handle orlever, by which it may be moved.

In the instance shown the end opposite that (No model.)

to which the bar E is connected is coupled by a bell-crank, 6 with a bar or rod, 0 having a handle upon its opposite end, and which may, if desired, have a segment-lever and catches for holding it in desired position, the object of employing the bar 0 being, for the sake of convenience, to enable the operator to start and stop the machine from the end opposite that adjacent to which the mechanism is located.

A pin, 0 upon the bar E enters a slot in the upper end of one arm, 0, of a rock-shaft, 6 which is mounted in a bearing on the frame B of the machine, and carries two arms, (2 6 to which the ends of the friction-band F are respectively connected.

By the vibration of the' rock-shaft induced by the movement of the bar to the left in Fig. l (which movement shifts the drivingbelt from the fast to the loose pulley) the friction-band F is pressed against the face of the brake-rim O and the movement of the vessel A is arrested coincidently'with the cessation of the application of driving-power to the counter-shaft D, and conversely the frictionband is released from the brake-rim coincidently with the movement of the bar E to the right to apply power to the counter-shaft.

I claim as my invention and desire to secure by Letters Patent 1. The combination, with a shaft, a brakedrum attached thereto, and a friction-band encircling said brake-drum, of a belt-shifter, a sliding bar or rod for operating said beltshifter, a bell-crank connecting the belt-shifter and sliding bar, and a triple-armed rockshaft, having two of its arms connected, respectively, to the ends of said friction-band, and the third to the operatingbar of the belt-shifter, the combination being and operating substantially as set forth.

2. The combination of a sliding bar carrying belt-shifting arms, an operating bar or rod, a bell-crank connecting said sliding and operating bars, and a rock-shaft having one long and two short arms, the long arm being slotted to receive a pin upon the said operating-rod, and the two short arms being adapted for connection to the ends of a friction-band,

substantially as set forth.
